Hey,.

The Category certificate has been issued by the state government and I don't think that should impose you ay problem. As what is sanctioned by the state government will be considered right for the state quota seats.

Any college will check you category certificate and not your caste. Soi think it's fine. But for safe side why don't you just contact the IPU authorities regarding this and discuss it with then to get a clear idea about your problem.

Hope that helps.

Thank you.
